Sadie and Gilbert are chosen to star in Harmony High's 21st century time capsule video, much to Val's dissatisfaction. However, Sadie wakes up on the day of filming with a giant wart on her nose, and her magical attempts to remove it results in her nose and Gilbert's whiskers disappearing. The two venture to the Labyrinth of the Lost and Doomed to retrieve their missing facial features, while Teepee and Lulu prevent Val and her pet dog Prince from starring in the video instead.

Sadie's practicing of the acceleration spell backfire when the spell is accidentally cast on Teepee, landing him a spot on the school's track team despite his lack of athletic fitness. Sadie decides to give Teepee a confidence potion disguised as perfume to help his self esteem, but merely ends up inflating his ego.

The Wardens of Magic task Sadie and Blaine with creating the best rainbow-summoning spell individually. Blaine's mentor, Cornelius, decides to help Sadie, despite Gilbert's cautiousness.

Desperate to avoid having to complete a magic essay and cleaning her room, Sadie creates two clones of herself to do her chores so she can go to Sam's barbecue party. When the clones end up going to the party themselves, she, Gilbert, Teepee and Lulu must try and make them disappear.

Sadie starts to have the worst of luck when Val begins to have the best of luck. Upon learning that Val has started wearing a secretly magical bracelet that makes gives her good luck at the price of all of Harmony suffering endless bad luck, Sadie attempts to retrieve the bracelet.
